Peru, a county     1     the Pacific coast of South America, is well-known for its diverse geography. time honored history and magnificent civilization. The county was the center of the powerful ancient Inca Empire in the 1400s and 1500s, when the Inca emperor     2     (live) in the now-famous site Machu Picchu.     3     nation was under the control of Spain from the 16^th century to 1821. It is because of this     4     Spanish is the main     5    (office) language of Peru.

If you are to visit Peru, you may consider spending a day or two     6     (wander) along the beautiful streets in Cusco,     7     was the capital of the Inca Empire from the 13^th until the 16^th century. It is also recommended that you     8     (pay) a visit to Machu Picchu, where you can admire the     9     (amaze) dry stone method of building. Being the world's catalogue, Peru is sure to leave an     10     (impress) on everyone.

I can remember some things about my childhood. Some are unhappy. I remember my first visit    1    the zoo. I saw a lion and    2    eagle. The lion was very lazy, and he    3    (sleep) all the time. He was very    4    (bore) to me. The eagles suddenly flew in the air and frightened me. I started to cry!

Of course some memories are happy. I remember the day when my father tried to teach me how    5    (ride) a bicycle. I wasn't very good at it. I said, “I don't want to do this!" But my father was very    6    (patience) and very soon he taught me how to do it. Now I ride my bicycle every day and I'm much    7    (fast) than my father! And I also remember my first day at kindergarten very    8    (clear). There were so many children! I only knew one of them, a boy    9    (live) in the apartment next door. I was very nervous. However,    10    we started playing with some toys, I soon stopped feeling nervous.

A little boy was spending his Saturday morning playing in his sandbox. He had with     1     his box of cars and trucks, and a shiny, red plastic shovel. In the process of creating roads and tunnels in the soft sand, he discovered a large rock in the middle of the sandbox.

    2    （determine）, the little boy shoved, pushed, and pried, but every time he thought he     3    （make）some progress, the rock tipped and then fell back into the sandbox.

The little boy continued. But his only reward was to have the rock roll back,     4    （injure） his chubby fingers.

Finally he burst     5     tears of frustration! All this time, the boy’s father watched from his living room window as the drama unfolded. At the moment the tears fell,     6     large shadow fell across the boy and the sandbox. It was the boy’s father.

Gently     7     firmly he said, “Son, why didn’t you use all the strength that you had     8    （avail）?”

Defeated, the boy sobbed back, “But I did, Daddy, I did! I used all the strength that I had!” “No, son,” corrected the father     9    （kind）. “You didn’t use all the strength you had. You didn’t ask me.”

With that the father reached down,     10    （pick）up the rock, and removed it from the sandbox.

So far mobile phones     1     (become) more and more popular among the middle school students, about which parents and teachers express great concern. It has been a hot issue so this February the Ministry of Education of China made a rule     2     primary and secondary school students shall not     3     (allow) to bring mobile phones to schools.

Many parents think this can protect students’ eyesight and make sure they focus     4     (they) on study. Besides, this can prevent them from     5    (play) online games for too long. If students do need to bring mobile phones to school, they should ask for their teachers’     6    (permit) with a written application (申请). However, some students are     7     the rule and still take their phones into school.

Personally, the whole     8     (social) should pay more attention to the physical and mental health of adolescents. Only by guiding them to use mobile phones     9     (proper) can they manage     10    (fix) their eyes on study!

You may remember back at the start of December,     1     China carried out their unmanned Chang’e-5 mission and the spacecraft touched down on the moon to collect samples for research. Now it     2    (success) returned to the Earth. This is the most significant event in China’s space field, and also one of the most notable space     3    (activity) globally. Chang’e-5,     4     (launch) by a Long March 5 heavy-lift carrier rocket early on Nov 24, is the nation’s     5    (large) and most complex lunar probe. It returned with 1,731 grams of lunar rock and soil to the Earth,     6    (mark) a historic accomplishment 44 years after the last lunar substances were taken back. The 23-day mission was China’s first space journey to claim extraterrestrial samples, making     7     the third country to accomplish the task, the first being the USA in the 1960’s and the second Soviet Union in the 1970’s.

The spacecraft     8    (enter) the Earth’s atmosphere at an altitude of around 120km. As soon as it was 10km above land, it released its parachute and landed smoothly in China's Inner Mongolia. Now the spacecraft has been air lifted to Beijing where the samples     9    (examine) by scientists very soon.

The mission’s results will contribute     10     mankind’s deeper understanding of the moon’s origins and the evolution of the solar system.
